Scientists have always claimed that the cell cycle starts with the birth of the cell and ends with the subsequent cell division. However, the latest research contradicts previous studies. Scientists at the Biozentrum of the University of Basel recently analyzed the behavior of E. coli bacteria cells and collected the data regarding cell division and DNA replication by using computational modeling. The data reveals that the cell cycle starts and ends with the initiation of DNA replication. The study has showcased the control mechanism of the bacterial cell cycle and can be used to study other biological processes and organisms.
